One of the popular methodologies of mead classification is by its alcohol strength (ABV%). There are 3 main mead types by strengths: session (or hydromel), standard and sack. Each range has specific ABV level:
– Session (Hydromel): This is a low alcohol mead, often served carbonated similar to beer. It will have a final alcohol by volume (ABV) level of 3.5 – 7.5%.
– Standard Mead: This is a mead of still wine strength, between 7.5 – 14% ABV.
– Sack Mead: This is a mead of high alcohol content, greater than 14% ABV.
This characteristic can be combined with other definitions f.e. metheglin of sack strength or melomel of session strength.
